My app works in the simulator but in the device NO. HELP :(

[erespia2]

Hello,

I have an application that sends a UDP datagram, and one who receives it.
In the simulator works, but when it happened to my nokia N95 8 gb, no
work. I have the .pro with the QT + = NETWORK, and TARGET.CAPABILITIES + =
NetworkServices.

When I test it on the devices, it asks me to choose a connection for
connect (WLAN) is connected, but does not communicate with other program
that is running on my computer. I tested with two simulators
two computers and it works.

The application is self-signed, but I have also signed with open
signed online (https: / / www.symbiansigned.com / app / page), and also not work.

Anyone can help me?

Thanks.

First question: How do you know it's not working? (Symptoms??)

Second question: Have you run it with the debugger to see where your code goes awry? Or at least inserted some sort of debug trace?

Third question: Are you accessing any data files in the execution of your program?

Hi!!, Thanks for answering.

The code I use is this: (Examples QT Nokia)

Receiver: http://doc.qt.nokia.com/latest/netwo...treceiver.html

Sender: http://doc.qt.nokia.com/latest/netwo...astsender.html

First Answer: It does not work out because it received messages. Probe the two programs (each on a PC) in the simulator qt, and it works, and test a program (recevied or sender) in the PC and one on my phone N95, and that sent from the mobile PC is less than , or sent from your PC does not reach the phone. Those are the symptoms.

Second Answer: Do not know how to use the debugger with the phone. I have several messages for the code, (qDebug), I can only see in the program being run from the PC. For example if I cast datagrams from the mobile to receive the PC, the SIGNAL jumps never have gotten the message.

Third Answer: What do you mean?, use the code that you attached by link above.

These examples are using local network UDP broadcast messages. On the other hand, your phone and PC do not form local network (you can check phone and PC IP addresses to ensure that).

I have connected my PC (laptop) for my WiFi router. The phone also I have it connected via WiFi to my router. The two are on the same network, is not it?, my laptop's IP is 192.168.1.33, and my phone is 192.168.1.34

Try QString QIODevice::errorString() aftrer writeDatagram() and readDatagram().

Try QString QIODevice::errorString() aftrer writeDatagram() and readDatagram().

How??

I'm testing after:

connect (udpSocket, SIGNAL (readyRead ()), this,
SLOT (processPendingDatagrams ()));

and after:

udpSocket-> writeDatagram (datagram.data (), datagram.size (),
QHostAddress:: Broadcast, 9050);
A place:

qDebug () <<QIODevice:: errorstring ();


And I get an error that it takes an object.
But when I create an object as QIODevice aux;
Will not let me because it is abstract or something like that.

As would prove?, Sorry for my ignorance

Thanks

qDebug() << udpSocket->errorString();

[erespia2]

qDebug() << udpSocket->errorString();

Ok.

I get this message on the console:

[Qt Message] "Unable to send a message"

Every time you send a datagram, the sender.

In the server, this message on the console:

[Qt Message] "Unknown error"

Is there a solution?

The same holds for the sign, since the run in through the Qt Creator
TRK for the phone, it runs with self-sign signature. But I tried
also to sign it (open signed), the. sis, separately and install it
the phone, and still not working. If I install it directly on the phone,
I have no option to use qDebug ().

This is my file. pro:

QT += network

TARGET = broadcastsender
TEMPLATE = app


SOURCES += main.cpp\
sender.cpp

HEADERS += sender.h

CONFIG += mobility
MOBILITY =

symbian {
TARGET.UID3 = 0xe85a5a74
TARGET.CAPABILITY += LocalServices NetworkServices ReadUserData UserEnvironment WriteUserData
TARGET.EPOCSTACKSIZE = 0x14000
TARGET.EPOCHEAPSIZE = 0x020000 0x800000
}

You can use QMessageBox::information() instead of qDebug(). However, problem is unlikely related to signing.

I get the same problem. Install the app on your phone, signing I did a certificate through the OPDA only for my IMEI phone. I get the list of available WLAN to connect to. I connect my network, appears on the screen phone, the icon connected, and when I send the datagram, still get the same error.

Every time you send a datagram

"Unable to send a message"

What can be happening?

I greatly appreciate your help.

[erespia2]

I still have the same problem.

Someone help me please?
